bnxt_en: add support for port_attr_get and and get_phys_port_name
This patch adds support for the switchdev_port_attr_get() and
ndo_get_phys_port_name() methods for the PF and the VF-reps.
Using this support a user application can deduce that the PF
(when in the ESWITCH_SWDEV mode) and it's VF-reps form a switch.
